Philco 610 and Zenith X334

[Electronic M]

They were still using Block caps at least in the power line to chassis application up until 1942.
I actually like block caps better than tubular paper caps. They are almost as easy to rebuild as papers are to simply replace, but are easier than papers to rebuild by a mile. Thus paper caps rarely get rebuilt by me, but block caps always get rebuilt (since it is easier/cheaper than removing them and installing terminal strips and new caps in their place). If I had the energy I'd rebuild all caps since it looks better that way IMO.
